Mounting the actuator
GESTRA continuous blowdown valves BA 46 and BA 47 can be retrofitted with a GESTRA actuator EF...
(BAE 46, BAE 47).
During operation moving internals can pinch one‘s hands or fingers. Do not touch moving
parts! The continuous blowdown valves BAE 46, BAE 47 are remote controlled and can
open and close very abruptly.
The terminal strips of the actuator EF ... are live during operation.
This presents the danger of electric shock.
Cut off power supply before fixing or removing the equipment.
